The simplest is to convert both into the same form. Whether you choose to go for two decimal numbers or two fractions is a matter of personal preference. Add the two parts together and you have your estimate.
6.9 or 69/10
39 is a whole number as in not a fraction or decimal.
0.4 as a fraction and decimal
No, the sum of a repeating decimal and a terminating decimal is never a terminating decimal.
A decimal number is one in which the place value of each digit is ten times the place value of the digit to its right. (... , thousands, hundreds, tens, units, tenths, hundredths, ... ) A decimal point is used to separate the units from the tenths. If a number in decimal form has non-zero digits after the decimal point then it is a decimal fraction. [There is one esoteric exception: if the decimal point is followed by an infinite string of 9s, then it is not a decimal fraction.] Thus 37.6 is a decimal fraction 0.6 is a decimal fraction 0.00000063 is a decimal fraction 37 is not a decimal fraction. 37.0 is not a decimal fraction. 37.999... recurring is no a decimal fraction [it is in fact = 38].
It depends on your level of numerical skill. You can convert the decimal to an approximate fraction and estimate the sum of the two fractions, or you can convert the fraction to an approximate decimal and estimate the sum of the two decimals or, if you are more able you just estimate their sum directly.
The range of a single number - with or without a decimal - is zero.
None of the items in the list.

i think you take the problem and turn it in to a improper fraction. estimate. add. Vola!
a decimal fraction means a fraction that changes into a decimal or a decimal that changes into a farction
If you are given a sum with a remainder, for example, 17 / 5 = 3 remainder 2, then you can convert the number to a mixed number by putting the remainder as the numerator of the fraction, and the divisor as the denominator of the fraction. At this point, the fractional part of the sum can easily be turned into a decimal by dividing the numerator of the fraction by the denominator - therefore, 17 / 5 = 3 2/5 or 3.4.
You don't need to estimate! The exact value is easy. 0.4 = 4/10 which is 2/5
0.21 is a decimal fraction.
